Hey Pulsar devs, I've been trying to set-up E2E encryption in Pulsar, following this guide: https://github.com/apache/incubator-pulsar/blob/ 9e3f390c8637c9804c234b01b8b396945a363af1/site/docs/latest/ advanced/Encryption.md
I've followed the steps in the guide, but I'm encountering issues around the BouncyCastle jar being used at runtime (I assume). For example, I see the following exception: Caused by: java.lang.NoSuchFieldError: id_hmacWithSHA3_224 at org.bouncycastle.jcajce.provider.digest.SHA3$Mappings.configure(Unknown Source) at org.bouncycastle.jce.provider.BouncyCastleProvider.loadAlgorithms(Unknown Source) at org.bouncycastle.jce.provider.BouncyCastleProvider.setup(Unknown Source) at org.bouncycastle.jce.provider.BouncyCastleProvider.access$000(Unknown Source) at org.bouncycastle.jce.provider.BouncyCastleProvider$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at org.bouncycastle.jce.provider.BouncyCastleProvider.<init>(Unknown Source) at org.apache.pulsar.client.impl.MessageCrypto.<clinit>(MessageCrypto.java:111) I've been putting BC jars into $JAVA_HOME/jre/lib/ext, adding BC dependencies to my build, but I haven't been able to fix these runtime issues. I think there's either something wrong with my (Scala) build env, or my system env. Does anyone have any ideas as to what issue might be? Or could someone perhaps share a simple, sample (gradle) project that creates a Pulsar producer and produces an encrypted message?
